SPRING-LINK BELT.

Application filed February 11, 1921, Seria1'N0.4 14,088. RenewedDecember 13, 1923.

To all whom itmmy concern:

Be it knownthat I, GABRIEL ABRAHAM, a citizenof the United States, and aresident of the borough of Manhattan, county, city, and State of NewYork, have invented certain new. and useful Improvements in Spring-LinkBelts, set forth in the following specification.

This invention relates to belts of the type worn as a trouser support.

The object of the invention is to permit the fabrication of the beltproper from durable, substantially inelastic fabric, arranged insections interconnected by resilient links, so that the belt as a wholeis yieldable in response to undue tension and will take up to but notbeyond a predetermined minimum. Although mere elasticity is of someadvantage in a belt, it is not an advantage to have indefiniteelasticity such as that inherent in a tensed rubber band or extensivespring. p

In carrying out the objects of the presentinvention, the belt proper maybe made in sections and the sections connected by resilient linksnormally held by a compression spring in their full take-u position, thetake-up position determining the minimum circumference of the belt whenbuckled.

The above and further objects of the invention will better be understoodby refer ence to the illustrative embodiment to which the followingclaim is directed, merely for purposes of illustration. This embodimentisdescribed below in connection with V the accompanying drawings, whichform a part hereof, in which like characters designate correspondingparts in the several parts, and in which- 7 Fig. 1 is a perspective Viewof a belt embodying the invention;

Fig. 2 is a front elevation, with parts broken away and drawn to anenlarged scale, showing a resi1ient ,.link of the invention; and V F'g.3 is a section through line 33 of Fig. 2, looking in the direction ofthe arrows.

A body belt A is shown made up of sections of leather strap 1, 2 and 3,the sec tions 1 and 3 being detachably connectible in the usual mannerby any convenient form of buckle 4. It is preferable that the buckle 4be the resilient buckle described in my prior patent granted to meFebruary 8, 1921, live buckle No. 1,368,009.

Resilient relief links B are employed to connect the belt sections 23and 2-1. In fact, it should be understood that the belt proper may besplit up into as many sections as desired, with the sections connectedby relief links B. In the drawings two are illustrated.

In this structure the link B comprises a substantially rectangular,plate 5, preferably of sheet metal and preferably somewhat curved, asindicated in Fig. 3, to fit better about the contour of the body. Theplate 5 is formed'along its opposite edges with parallel, inturned guideflanges 6 and 7 and has a spring lip 8, inturned from its body portion9, to form a retainer for the end 10 of the zigzag compression spring11. Sliding within the flanges 6 and 7 of plate 5 is a slide-plate 12,which may have struck out flanges 13 and 14:, tending to space it apartfrom the body portion 9 to form a working chamber for the spring 11.This slide-plate 12 likewise has a spring lip 15 to be engaged by theend 16 of compression spring 11, so that the compression spring 11.reacting against the lips 8 and 15, tends to separate the plate 5 fromthe slide-plate 12. In the embodiment illus trated the end edges of thelink B are provided with perforations 20 and 21 through which eyes 22and 23 of bails 24 and 25 are fitted. The perforations 20 are positionedat a shorter distance from the spring retaining lip 15- of plate 12 thanis the distance from the spring retaining lip 8 on plate 5 to the end ofthe body portion 9 of this plate 5 and a symmetrical positioning forthe'perforatio-ns 21 is made so that the eyes 22 and 23 serve as stopsto preserve the assemblement of the link while the bails 24 and 25 serveas convenient means to mount the looped ends 26 and 27 of the beltportions. Obviously the perforations 20 and 21 could be made of a sizeto take the strap ends themselves, in which case the straps would serveas stops to preserve the assemblem-ent of the link.

The compression spring 11 thus may function solely as relief, itsstrength being sufiicient to maintain the plates 5 and 12 in theirnormal position, shown in Fig. 2, until eXcessive strainis applied tothe belt, in which case the spring 11 will yield under compressiontemporarily to lengthen the belt A whiclnnpon the removal of theunduestraiin will resume its normal length Without constriction beyondthe degree desired. V

lVhat I claim and desire to secure by United States Letters Patent is Aresilient relief link for belts comprising an elongated platehavingedg-eflanges spaced apart from and parallel With said plate and onone end a spring-retaining lip; a slide-plate sliding Within saidflanges and having an end spring-retaining lip; a compression springreacting against said spring-retaining lips and located between 15-S211Cl plates; and one of said plates being' to its end and a beltconnection passing through said perforation'and serving as 'a stop tolock the parts together.

In witness whereof I have signed my name to this specification, this25th day of 2 January, 1921,- at New York, N.--Y. v V
